Extension of the simulation library PROPOSAL to propagate electromagnetic shower components — •Jean-Marco Alameddine, Jan Soedingrekso, and Maximilian Sackel — TU Dortmund, Dortmund, Germany

PROPOSAL is a Monte Carlo simulation library, usable both in C++ and via a python wrapper, used to describe the propagation of highly energetic particles. These particles can, for example, be induced by atmospheric air showers or produced from interactions of astrophysical high-energy neutrinos with matter, observed with experiments such as the IceCube Neutrino Observatory. Previous versions of PROPOSAL focused on a precise description of muon and tau propagation. In a recent update, both photon propagation and a more precise description of electron and positron propagation were implemented as well. This allows PROPOSAL to be used as a propagator for electromagnetic shower particles, for example in the upcoming eight version of the extensive air shower simulation framework CORSIKA. In this talk, the recent update of PROPOSAL is presented with a focus on the physical description of the new processes as well as comparisons with alternative propagation models such as EGS.
